Plain Bearings: Also known as bushings or sleeve bearings, plain bearings consist of a simple cylindrical design without rolling elements. They rely on a sliding motion to reduce friction and are often used in low-speed, high-load applications such as in agricultural machinery, construction equipment, and industrial machinery. Plain bearings are valued for their ability to handle heavy loads and operate in harsh environments.

It's important to note that while thrust ball bearings have these limitations, they are still valuable components in many applications where axial load support is the primary requirement. Understanding these disadvantages allows engineers and designers to make informed decisions when selecting bearings for specific applications, ensuring that the chosen bearings align with the operational demands and load conditions.
